I'm confused as to why anyone would buy this in stock form right now. (unless SLI, but why not wait for CLC?)
This card has good (really good) OC potential, and the better performers will not be using the stock cooler.
I went SLI, so the blowers work well for that.
I have a mid tower case and the single rear exhaust port is already used by my CPU CLC fan. I'd need to get a new case with two more ports in the back for the cards. Not worth the hassle for me.
Cost - already stretching it at $650.00. Small increases not worth it to me.
I only OC my video cards a small amount, no added voltage or anything, just so I feel like I OC'd them to get that little extra for free. I feel like if a stock GPU can't run a game well, adding a big OC won't make me happy either. When 2 cards can't cut it, its time to ditch them.
For instance, there is no pair of GTX 780ti's in the world, regardless of their insane uber voltage OC that would make them last any longer than a stock pair IMO. The gameplay experiences I've had with OC'd GPUs was not worth the effort for me, so I leave them alone for the most part. CPU's is a different story completely. If I had only a single GPU, I'd be all over OCing the crap out of it. Two is already overkill and lets the CPU stretch its legs fully.
